Please support SMIL animations too. SMIL is the best declarative language for animations in the world, there is nothing like it. It's so powerful and still human readable. And offers advanced timing and perfect synchronization between animations and sound effects, something very rare even in closed and proprietary software animation formats. SMIL is the THE standard format for animations, used both for the Web as part of SVG:

Currently in IE you need to use a polyfill based on the web animation standard to run SMIL animations. Eric Willigers from Google has created the official SMIL polyfill implemented entirely on the Web Animations API. You can find it here:

But the web animation standard is NOT a declarative language for animations, you still need SMIL to describe animations in browsers.
Many professional animation packages can import, edit and save directly in SMIL. With SMIL support you can do in minutes things that would require days to do otherwise. It also provides an universal interchange format for animations. SMIL is the "lingua franca" of vector animation. Please support it if you want to make a browser capable of amazing animations .

I have very little confidence MS will implement even the most important/popular aspects to SVG2 given that they absolutely refused (and still have) to implement the foriegnObject element. IE is the only browser that has never implemented the foreignObject element while ALL other browsers have implemented it since their earliest versions AND the foreignObject element has been around since some time before 2003.

I will vote for this when the SVG2 spec is including the stroke-position property to be able to have the stroke inside or outside of the path - but it's deferred. It's one of the things I'm really urging for.
